IB: cxgb3: delay freeing mem untill entirely done with it
Sure, it's just the pointer value we use, but the coverity checker
complains about a use-after-free bug and it really does seem cleaner
to delay freeing until we are entirely done with the memory. So,
rearrange the code to move the kfree() later untill we are completely
done.
Trivial and harmless, but nice IMHO.
